Latest update from Stytch

Type: Incident Duration: 5 hours and 18 minutes Affected Components: Message deliverability Aug 18, 00:00:00 GMT+0 - Postmortem - We extend our sincerest apologies for this outage. On 17 August 2026, between 02:15 and 05:15 PT (09:15–12:15 UTC), all outbound email from Stytch failed, including email magic links, email OTPs, and password reset emails. Service was restored at 05:15 PT. **What happened**: This outage was triggered by abuse of free-tier email sending, a pattern we defend against continuously. In this case, our abuse controls did not engage in time, and a large volume of spam was sent before we intervened. That volume exhausted our sending quota with our primary email provider, which normally handles the majority of traffic. Automated failover and alerting fired, and our on-call engineer fully failed over to our secondary email provider within 20 minutes. That failover appeared to succeed: The secondary provider accepted our sends and reported them as successful 200s. Howev
